Update: 09:40 We've just added a detailed synopsis thanks to Other Brother for the details

As some of you may know, ABC held a screening of What They Died for last night at the Live Lost event. You can see the photos here.

We're received some very spoilerly info from this episode from people who were at the event. I strongly recommend that you DO NOT read these unless you want to be spoiled for this episode. Also please do NOT post any of this info outside of this thread.

NOTE: There are additional detailed spoilers in the comments from people who attended.

Well, I just got back a little bit ago from Lost Live. It was awesome! Overall there were about 20 actors there, plus Damon and Carlton, the writers and Jack Bender. The orchestra set was great and it was a perfect exclamation point on the series to hear the music performed live.

The penultimate episode was shown in it’s entirety and I thought it was great; one of the best of the season so far. Here’s the spoilery stuff:

Sideways Jack wakes up with the familiar blood stain on his neck and goes to eat breakfast with David. David makes sure Jack is going to his concert that night and Jack says he would be and inquires if David’s mom will be there. Jack gets contacted by Oceanic telling him his father’s casket was located, but it turns out it’s actually Desmond on the phone. On the island, Jack patches up Kate’s shoulder and Kate laments that Locke killed Jin and Sun and that they have a daughter, one that Jin will now never see. Kate says that they have to kill Locke and Jack agrees. Jack says that if Locke wants Desmond, they need to get to him first and they (Kate, Jack, Hurley and Sawyer) head off to the well to retrieve him. In sideways world, Desmond watches from his car as Locke gets out of his van; his first day back at school after being run down. In a similar situation Des starts the car and seems poised to run Locke down again until Ben interrupts him and stops him. Des gets out and says he wasn’t trying to hurt Locke, but help him. Ben asks how and Des starts punching him; at which time Ben begins to have flashes of his “other” life. On the mend in the nurses office, Locke arrives to check on Ben and Ben tells him the story as Locke calls the police. Ben stops him and says that he believes Desmond when he said he was trying to help. Alex meets up with Ben outside the school and invites to drive him home with her mom. At first Ben declines, but then a “cleaned up and non crazy” Rousseau insists. Back at their house after dinner, Ben asks Danielle what happened to Alex’s father. She says he died when she was 2 and muses that is why Alex has taken to Ben so much; he has an interest in her and believes in her and is the father she never had. Ben gets misty from hearing this.

Back on the island, Richard, Miles and Ben are heading to Ben’s house to get his stash of C4 to blow up the plane. While there, Zoe and Widmore arrive. Widmore explains that after the freighter was blown up, Jacob visited him and explained what he must do. Widmore orders Zoe to go sink their boat and she leaves. Widmore explains that he brought Desmond to the island because of his immunity to electromagnetism. Zoe calls up on the walkie explaining that Locke has arrived on the island. Widmore orders her to return and when she is on her way Widmore says they all need to hide in Ben’s closet. Miles leaves on his own while Ben and Richard decide to confront Locke; thinking they can either buy time or get him to leave. With Widmore and Zoe in the closet walk outside. The black smoke slams into Richard and tosses him into the woods. Ben sits and Locke approaches and says that there are some people he’d like Ben to kill and in exchange, Ben can have control of the island after Locke leaves. Ben accepts and tells him that Widmore and Zoe are in his closet. Locke promptly slices Zoe’s throat and tells Widmore that if he tells him what he wants to know he won’t kill penny when he leaves the island. At first Widmore doesn’t seem to trust him, but relents and tells him of Desmond. When Locke asks why Desmond, Widmore doesn’t want Ben to hear. Ben turns around and he whispers inaudibly into Locke’s ear. Suddenly Widmore is shot numerous times by Ben, with Ben explaining that he (Widmore) “Shouldn’t have the opportunity to save his daughter” and then asks Locke if there are others he wants him to kill.

In the woods, young Jacob appears to Hurley and demands his ashes from Hurley. He takes them and runs away and Hurley gives chase, and comes upon adult Jacob in the woods around a campfire. Hurley brings Jack, Kate and Sawyer to Jacob, who they can now see and communicate with. Jacob explains that he made a mistake when his actions made his brother into the smoke monster and he knew that eventually he’d find a way to kill him; so the candidates have been his preparations for his eventual demise. And that protecting the island is what the others “have all died for.” He says that he must have a successor before the fire burns out; once it does, he is gone for good and “it would be very bad” if there isn’t someone to take his place. Sawyer complains that his life was fine before Jacob brought them there, but Jacob interjects that they were all lost, lonely and broken, like he was. Kate asks why she was crossed out and Jacob explains that it’s “just chalk on a wall, he crossed her out because she became a mother and the job is still open if she wants it”. No one accepts at first, until Jack stands and says this is what he was meant to do and accepts the “job”. Jacob explains that the light is the heart of the island and is what must be protected from extinguishing; which is what MIB wants to do. Jack asks if they’re supposed to kill him (MIB) and Jacob says that he hopes they can. Jacob gets a cup from Jack, says a “prayer” to the water and gives it to Jack to drink; when he does, Jacob says “Now we are the same”.

In sideways world, Locke goes to Jack and explains that maybe fate is what cause his accident and maybe Jack is supposed to fix his spine. Jack accepts (after the uttering of a few familiar phrases).

On the island, Locke and Ben reach the well to see that Des is not there. Ben asks what it was that Widmore said to him about Desmond. He says that Des was Jacob’s “Failsafe” in case all of his candidates were killed; but that Desmond will be useful to Locke now because Desmond can do what Locke has never been able to do, “Destroy the island”.
